Solution

The correct option is D
Evaporation

Seawater contains a large amount of common salt and the salts of other elements dissolved in it. Near the sea-shore, the sea water is collected in shallow pits and allowed to evaporate under the sunlight. In a few days, the water evaporates, leaving behind salt. So, salt is obtained from seawater by the process of evaporation.
